The battery storage system uses retired vehicle batteries from the Opel Ampera to temporarily store electricity. These stationary batteries in their “second life” serve to balance consumption peaks and thus stabilize the power grid.

A total of 18 vehicle batteries are reused in the battery storage system, with a capacity that could charge eight electric vehicles simultaneously – or supply a four-person household with electricity for a month.

The batteries are stored in a standard shipping container that can be transported with little effort. Charging stations are attached on the outside to allow electric cars to be charged directly from the container.
